NVIDIA GeForce GTX 1070 Boost Clock is 1683 MHz
Though I actually already added these numbers into our 1080 review yesterday, apparently today it is news. Nvidia posted specs and these now include clock frequencies as well. The 8GB GDDR5 memory will run at an effective clock frequency of 8000 MHz.
The GeForce GTX 1070 has the same GP104 GPU housed on it's PCB as the 1080, however it'll be cut-down GPU with stripped away segments, it has 1920 shader processors. This means it is has 15 out of the 20 SMs active (15 streaming multi-processors x 128 shader cores). The memory is clocked at 2000 MHz actual which is 8 GHz (GDDR5-effective) at a memory bandwidth of 256 GB/s. Single-precision floating point performance at 6.45 TFLOP/s. The card will start at 379 USD with the founders edition (reference card) costing 449 USD. Below an overview of the specifications:

no doubt its going to be a good card, but to all of you wanting to sell your cards my advice wait till after Hilbert review then decide.

Reference Titan X
At 1075mhz
So what you're saying is the 1070 clocks will only be locked at reference speeds and only 9 series cards can be OC'ed?

Selling 980's to buy 1070 is not a bad idea especially if you plan on getting a second some day to SLI them.
Like i have said in all the other 1070 threads, a reference 1070 is almost identical to the 980 in specs.
Of course the 1070 will get more Vram @ a higher clock, will cost less and use slightly less power but it's not going to smash the 980 by much.
Again it's basically like say a G1 980 @ 1650+mhz on the core and 8000 on the memory.
Reference 1070's = Highest scoring 980 overclock.
A Kingpin or other top end card will be 1900+mhz on the boost and may match a TI.
None of the new tech would i use anyway so it's no different than Maxwell to me. Same DX12_1 support and nothing that new really.
I'm gonna skip Pascal and wait for Volta because by then hopefully DX12 has matured into a better API and Volta should bring real DX12 support.

It is as fast as Titan X with no boost. When that 1070 is in boost clocks. Once you add boost and oc the titan. No matter how much you oc the 1070 it ain't gonna pass it on air or water.
